Yeah, new map would be better. Can't even keep all my valuables in my inventory either.

Another method I came across would be having people move their precious stuff to the nether though, then only deleting the main world file. Dunno if that's smarter now that people have already been screenshotting their inventory, but it's an option.

That's... Actually not a bad idea. Except for one problem.Wouldn't we generate a new entrance away from our crap when we make the new map? We'll need something like Rei's Minimap to mark a waypoint to our stuff in the nether.

Well, people should make sure to log out in the Nether, with their stuff. Even if they didn't, I think they would spawn in the overworld at the same coordinates on the new map, so a portal would take them somewhere close to where they left it.

I think the player's coordinates are saved in their own file, rather than the world's, but I can test it real quick.

EDIT: Yup, player position is saved in it's own file. The only thing that needs be deleted is the overworlds region file, which basically only contains block data. Even if it weren't like this, deleting it couldn't impact the players if they were in the nether, since that's a different region file. Level.dat can also be deleted if a new seed is preferred, but I don't think that'll be nessecary, since the new biome generation will probably make the same seed look very different.

I have nothing against building a new houses, reigning in animals and collecting the basic resources again. I do have something against building the exact same Iron Farm again in survival mode, that shit be tediously specific, and having to farm for the stacks of redstone and diamonds I have to use for future projects again. However that's done the easiest, I'm down for.

Out of curiosity, do you plan to have a normal map, or an AMPLIFIED map?

I've been playing with friends on a handful of low populated Amplified servers, and imo it's beautiful. With more possibilities too. Earlier today, I was on top of a high rise(bow and arrows in hand) watching friends about 30-40 blocks below. They were clearing a forest at night.We labled the areas of the forest. I was telling them where mobs were spawning, and if they agro'd. Got a couple snipe kills. :3

It was an experience that we just haven't had. All this was around 200 height. Just asking :p

Amplified maps are pretty, but they're also very impractical. You have climb mountains and jump ravines to get anywhere, you can't find a decent plot of flat land to build on, they're many dark overhangs that constantly spawn mobs AND, as they mention, it's a resource hog, not everyone may even be able to play on a amplified map. I'd rather we just use a standard one.
